To all whom'ii may concern.

Be it known that I, GUY ii-Hooves, a citizen of the United States,residing at Sherman, in the county of Grayson and State of Texas, haveinvented certain new and useful improvements in Recording Devices, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to recording and indicating devices for grainmills and more particularly to certain improvements in devices of thatcharacter shown and described in my prior application for patent filedApril lth, 1911, Serial Number 618,877.

The present invention object the provision of improved means foraccurately recording and indicating the weight of a continuously flo'ing stream of material and for indicating the number of pmindsyn'oducing barrel of flour irresgecti\ o of the gradeof such material.

Another object of the invention is to provide improved means formounting and. actuating the indicator arms whereby the weight of theflour and of. the feed arc simultaneously recorded.

Still another object of the invention is to provide a device of thewhich is of comparativel simple construction and which is so arrangedand mounted that absolutely accurate results are assured.

\Vith the above and other objects in view, the invention consists of thenovel features of construction, combination and arrangement of partshereinafter fully described accompahas for its orimarv nymg drawings, inwhich- Figure l is a.-fro.ut elevation of a machine embodying myii'nprovemcnts; Fig. 2 is a side elevation, the cylinder casing beingshown in section; Fig. 8 is an enlarged deon the line of Fig. 2; Fig. 4is a detail sect-ion taken on the line 5 is a detail perspective view ofthe jointed pencil carrying men'iber and portions of the intermediateindicator rods to which said member is connected; Fig. 6 is an enlargedvertical section taken on the line 6 6 of 1; Fig. 7 is a detail of theindicator arms; and Fig. 8 is a detail section taken on the line 8 8 ofFig. 2'.

receiving cylinder means to be actushaft having a material arranged onone end, and

is ovcrbalauced by ated when the cylinder the weight of the material toindicate the weight of such material. These broad features ofconstruction a re retained in 'the present application, wherein thespecific improvement resides in the provision of means whereby theweight of the material passing through the machine is not only indicatedbut also permanently recorded.

Referring now more part .ularly to the" accompanying drawings 5designates a suitable frame structure which is centrally di vided by avertical wall (3. horizontal. beam 1' extends through this wall and issupported at its ends by the uprights S which are secured to the end. ofthe frame. To the beam 7 and upon each side of the wall (3, a pair ofdepending hanger rods 9 are rigidly secured. in the lower ends of. theserods a longitudinally disposed pivot shaft 10 is mounted. This shaftextends through a tubular hub or sleeve 11. To the sleeve 11 thecoupling members 12 are secured. These members extend a t right anglesto the pivot shaft 10 and are of T-shaped form. To the central dependingextensions of said cou pling members the similar members 13 areconnected, said latter members 1i roviding hearings or supports for thecylinder shaft 14. 0 one of the members 12, a. rod 15 is connected andthe other of said members carries an attaching plate 16 which is rigidlybolted or otherwise secured to the case 0 18 of the cylinder 17 which isrigidly fixed upon one end of the shaft 1%. To the rod 15 acounter-balancing weight 19 is secured, said weight normally equalizingthe weight of the cylinder 17 so as to n'iaintain the rod 3 and thecylinder shaft in a hor ontal p no. The cylinder casing 18 is povided atits top with an upuardly extending tapered inlet neck 20 in which thelower end of a flexible conducting tube 2 is disposed. The upper end "ofthis tube is fixed to the top, of the frame 5 beneath the hopper intowhich the chute deposits the mate rial. The end of the rod 15 adjacentto the 7 weight 19 is connected to a suitable dash pot 24 which preventsany unsteady movement of the parts and absorbs all shock or jar theretowhen the receiving cylinder returns to its normal position.

Upon the cylinder shaft it and between f the manner in i the members 13a sprocket Wheel is secured, and this sprocketwheel is traversed by anendless chain 26 which passes around a similar sprocket on the driveshaft 27 which extends through the lower end of the frame structure.

It will be understood that the foregoing description of parts whichrelates to the mounting of the material receiving cylinder and themanner in which the same is balanced, is precisely the same upon eachside of the central vertical wall 6 of the-frame, and that sucharrangement may be still further multiplied if desired.

Particular attention is called to the fact that the point of connectionof the power transmission chain 26 to the cylinder shaft is directlybelow the pivot shaft 10 whereby the cylinder and its case aresupported.

I will now proceed with the description which an-accurate determinationand record of the amount of material. passing through the machine andalso the number of pounds to each barrel of flour milled, is obtained.

WVith the above objects in view, 1 provide the inwardly extending rods28 which are secured to the rods 15. The rods 28 each carry a pair ofvertically disposed bolts 29. To the upper end of one of these bolts thelower end of a connecting rod 30 is pivotally secured, the upper end ofsaid connecting rod being pivote to the angular extension 32 formed onthe lower end of an indicator arm 31. This arm is vertically disposedand is formed at the juncture of the extension 32 therewith, with asleeve 33 which is rotatably disposed upon a bolt 34 which is threadedat one end in a bar 35 rigidly fixed upon the face of a verticallydisposed plate 36. The upper end of the arm 31 is provided with a leadreceiving tube 37, and to said arm one end of a leaf spring 38 isrigidly fixed, the free end of said spring being adapted to engage thestick of lead and normally hold the same in engagement with the surfaceof a chart indicated at 39 upon which the weight indications arerecorded in the operation of the machine.

The vertically disposed substantially 'parallel rods 40 are pivotallyconnected at their lower ends to the other of the bolts 29 carried bythe rods 28, said rods 40 extending above the top of the frame 5 uponopposite sides of the vertical wall 6 thereof. The upper ends of theserods are guided in the eyes 42 which are formed upon 'the upper ends ofthe vertical bars 41, said bars being rigidly fixed at their lower endsto the horizontal bar 35. It will be observed that the rear face of thebar 35 is spacedfrom the face of the plate 36 so as to permit of thepassage of the chart paper therebetween,

said bar serving as a guide for the paper same closely upon and actingto retain the The chart paper is the face of said plate.

preferably, arranged upon a roll indicated at 43 and mounted in the rearof the plate 36. The upper end of the plate 39 is slightly curved asshown at 39 so as to allow the paper to pass smoothly thereover andobviate liability of tearing the same.

The upper ends of the rods 40 are angularly disposed as indicated at 40and threaded to receive the nuts 44. To these threaded ends of said.rods the sections 45 of a jointed marker are connected, said sectionsbeing pivotally connected to the pairs of similar sections 46 which areadjustably connected by the short rods 47. The inner elements 46 of eachpair are also pivotally connected, and in said ends and concentric tothe pivot a stick of lead is arranged. leaf spring 48 is secured to oneof the elements of the marker and bears at its free end against the leadto hold the same in contact with the surface of the chart as describedin arms 31.

In order to continuously move the paper chart in the passage of thematerial through the machine, I provide the rollers 49 which arerotatably mounted in the supporting legs or standards 50 upon which theplate 36 is mounted. To one of the roller shafts, a worm gear 51 issecured, and said gear meshes with the teeth of a worm 52 formed upon ashaft 53 which is mounted in suit able bearings arranged on the frame 5.

sprocket 54 is rigidly fixed upon the end of the shaft 53 and istraversed by an endless chain 55 which passes around a similar sprocketon the drive shaft 27. The other ends of the rollers are provided withthe intermeshing pinions 56 so that said rollers are at all timespositively rotated at the same speed.

In the use of my improved mechanism,

the chart paper is passed over thefront face of the plate 36 and behindthe bar 35, and

inserted between the opposed'engaged surface portions of the rollers 49.As power is imparted to the cylinder shaft with the drive shaft, thewheat or other grain products is admitted to the hopper 22 from whenceit is deposited through the conveying tube 21 into the peripheralgrooves or pockets 17 which are provided in the receiving cylinder 17.The weight of the material as it strikes the periphery of the c linderovercomes the counter-balance weight 19 and causes the end of the shaft14 carrying the cylinder to lower, 12s

the cylinder and its case of course moving therewith. Thus the rod 28will be elevated, thereby forcing the rod 30 upwardly and oscillatingthe indicator arm 31 upon its pivot to move the pencil point carriedthereby connection with the indicating shaft 14 through the medium ofthe chain 26 connecting said 115 bodily movement of said cylinder by theWeight of the material thereon to record the weight of said material.
